1. **Problem:** A 10m length of string weighs 350g. How long is a string that weighs 875g?
2. **Formula:** Weight is directly proportional to length, so \( \frac{weight_1}{length_1} = \frac{weight_2}{length_2} \).
3. **Calculation:**
\[ \frac{350}{10} = \frac{875}{x} \]
Cross-multiply:
\[ 350x = 875 \times 10 \]
\[ 350x = 8750 \]
\[ x = \frac{8750}{350} = 25 \]
4. **Answer:** The length of the string that weighs 875g is **25m**.
